I ran the 12v 5 minutes test on my aar. After the 5 minutes, it closes but still allow very small amount of air to go by. Is that normal ?

Get it to operating temp and clamp the hose between AAR and manifold with a needle nose vice-grip.

I was reading this article also. and it may be something that I have to live with. http://members.rennlist.com/pbanders/idle.htm Idle mix can be made richer with the idle screw on top of the e.c.u. Clockwise is richer. If it is lean it will hunt. If you increase the idle speed with the idle valve on the throttle body the hunt may go away. It has been my experience with my d-jet that the mps was out if spec and set too lean, or on one occasion going bad ad was too lean. Some here will say as the book says that it is supposed to default rich and I have had that too one one occasion but then twill not hunt, and you would have a low idle, also lots if soot on the plugs and tailpipe. .you should run more on the rich rather than lean. But I digress. Has your mps been tested for leak? And can you tell if it has been opened up? ? Look and see if the epoxy plug has been removed. If so it has been at some point adjusted and may be set too lean. Che k those things an let me know what you find. But try the e.c.u. idle adjust. And make sure the hose to the aar is not sucking any air. If you have not gotten it to close yet , you can just block off the hose for now after it is warmed up ans previously suggested. |
